Subject: [Expat-discuss] Suspend/resume and abort patch available
Message-ID: <000e01c3a229$471456e0$9e539696@citkwaclaww2k>

A new patch for Expat is available that adds
suspend/resume and abort functionality to Expat.

Check out patch #835123: Suspend/Resume functionality, 
http://sourceforge.net/tracker/index.php?func=detail&aid=835123&group_id=10127&atid=310127.

This should give a clean way to abort parsing or suspend and resume later.
The API has been updated as follows:
- Added XML_STATUS_SUSPENDED to enum XML_Status
- Added function XML_StopParser()
- Added function XML_ResumeParser()
- Added more error codes and strings

Usage is simple: from within a handler call-back call
XML_StopParser(parser, resumable);
If resumable is true, XML_Parse(Buffer) returns
with XML_STATUS_SUSPENDED, otherwise it returns
with XML_STATUS_ERROR and the error code is XML_ERROR_ABORTED.

You can resume parsing simply by calling XML_Resume(parser),
which will return the same status and error codes as XML_Parser(Buffer).

This API is subject to change, especially if this patch doesn't make
it into release 2.0, as an API overhaul is planned for release 3.0.

It seems to be working well for me, passes all XML_Test_Suite tests,
but I would really like it to be subjected to some heavy duty testing.

I know there was a discussion of this some time ago, but I would like to 
check something.
When the parser comes across a tag like <plus/>, which function gets 
called? Is <plus/> treated as a start tag, an end tag, both a start and end 
tag, or character data?
Thanks,
Heather

This case is treated EXACTLY as if you had <plus></plus>,
so the start_element function is called first, then the 
end_element is called. In fact your code doesn't even
know whether the data came from <plus/> or <plus></plus>.

This is somewhere in the manual ;-)

Thanks Carlos for your help in understanding the treatment of empty tags.

I'm now trying to run the example program outline.c (on Windows 2000 using
the Borland compiler). The program compiles and runs fine, but I was
wondering how I tell it what to parse. The program reads from stdin.
However, while the program is running, any characters I type in are simply
ignored. Is this something to do with the encoding, or is the program
expecting an input from somewhere else? If the manual explains how to set
the encoding, I must have missed it. I know I can use US-ASCII, UTF-8 etc,
but simply passing these values to XML_ParserCreate (e.g.
XML_ParserCreate(UTF-8)) results in a compilation error, as UTF-8 is an
unknown symbol.

I've also tried changing the program to read from a (UTF-8 or ASCII) text
file, without success. The file is not copied to the buffer, even using
strcpy rather than the Expat functions. However, it is copied to another
character array r.

Does anybody know how to deal with this? I know this must seem very basic
to some of you, but I would really appreciate some help.

Thanks,
Heather

Subject: [Expat-discuss] Split UTF-8 sequence possible?
Message-ID: <D74A7429-1398-11D8-966C-00039351392E@xltsoftware.com>

Having just overcome the newbie problem of not realizing that expat
feeds UTF-8 sequences to my handlers, I'm now wondering if
expat ever splits a multi-byte UTF-8 sequence across two calls to my
character handler callback.

For example, say there's a non-ASCII accented character
in its input character data (however it may have been encoded).
expat will want to send me a two-byte UTF-8 sequence.  If there's
only one byte left in the output buffer, will it (1) call my character 
data
callback with the buffer one short of capacity, and save the two-byte
sequence for the next callback, or (2) put the first of the two UTF-8
bytes in the buffer, call my callback, and then put the second at the
start of the buffer for the NEXT callback?

I'm really hoping #1. Can anybody confirm this?

Thanks -- Jeff Garbers

I am pretty sure Expat reports complete characters, as nothing
else makes sense. There are no output buffer boundaries forced on Expat.

Try running it by redirecting a file to standard input:

  outline.exe <myfile.xml

Works for me,

Hi,

I know almost nothing about what it takes to run in kernel space.
If you enlighten me, maybe I can tell you if Expat fulfills
your requirements.

If its just about memory handling - Expat allows you
to plug in your own memory management.

I think it is. But it would be even better to use no memory other than the
stack at all.
I only need SAX functionality.

Does Linux (I assume that is your OS) support the alloca() function?
In that case you could pre-allocate a chunk of memory on the stack
(in the function that creates and frees the parser instance),
and let your custom memory handler call-backs allocate from this
buffer. Expat tries to re-use memory internally and does not
call back on the memory manager that often.

  1. The example pointed to on the web page is from 99, and the

????!!

  2. Also same problem with the windows nt lib.

  3. Can i find an example app that exercises all the api's, even if 
trivially? this is driving me crazy!

I don't know what documentation you were looking at, but I don't think
it was anything I wrote, or that gets packaged with Expat.  Expat can
provide some information from the DTD.

There are several examples included with Expat; the xmlwf application
is perhaps the most thorough.  If you have additional questions, feel
free to ask here; you may need to be more specific in order to get
useful help.

Subject: [Expat-discuss] Read XML like file
Message-ID: <00c601c3aac6$7e46edd0$647ba8c0@regis>

I would like to use expat to read an XML file that does not have a root
element.
This file contains records, for example it could be some ting like that:

<REC><TIME_STAMP>10:40:00</TIME_STAMP><DATA>some data</DATA></REC>
<REC><TIME_STAMP>10:40:23</TIME_STAMP><DATA>some other data</DATA></REC>
<REC><TIME_STAMP>10:40:35</TIME_STAMP><DATA>some other data to</DATA></REC>
...
<REC><TIME_STAMP>10:45:12</TIME_STAMP><DATA>some data</DATA></REC>


That way, records can be appened to the file without having to read it
completely and rewrite with the new records

Is this possible, even if it is not fully xml compliant?

TIA

Hi all,

With expat 1.95.7 on ia64, the new XMLCALL macro causes lots of complaints from
gcc.  The 'cdecl' attribute is not supported on that platform.

Subject: [Expat-discuss] Result of outline.c from the win32 expat binary
Message-ID: <3FB9AC5E.60800@info.com.ph>

Good Day!

This is my first time to develop applications using expat.
I have successfully build the win32 expat binary with Visual
Studio and of course compile and run my expat applications.
As a first timer i have successfully compile elements.c and
outline.c in the examples directory. I just want to confirm if
this is the correct output that i am getting out from outline.c

My sample.xml file looks like this:

<nutrition>
<daily-values>
<total-fat units="g"> 65 </total-fat>
<saturated-fat units="g"> 20 </saturated-fat>
<cholesterol units="mg"> 300 </cholesterol>
<sodium units="mg"> 2400 </sodium>
<carb units="g"> 300 </carb>
<fiber units="g"> 25 </fiber>
<protein units="g"> 50 </protein>
</daily-values>
<food>
<name>Avocado Dip</name>
<mfr>Sunnydale</mfr>
<serving units="g"> 29 </serving>
<calories total="110" fat="100"/>
<total-fat> 11 </total-fat>
<saturated-fat> 3 </saturated-fat>
<cholesterol> 5 </cholesterol>
<sodium> 210 </sodium>
<carb> 2 </carb>
<fiber> 0 </fiber>
<protein> 1 </protein>
<vitamins>
     <a> 0 </a>
     <c> 0 </c>
</vitamins>
<minerals>
     <ca> 0 </ca>
     <fe> 0 </fe>
</minerals>
</food>
</nutrition>

i execute outline.c with this syntax:
     outline.exe < sample.xml
and got this output:
n
   d
     t u='g'
     s u='g'
     c u='m'
     s u='m'
     c u='g'
     f u='g'
     p u='g'
   f
     n
     m
     s u='g'
     c t='1' f='1'
     t
     s
     c
     s
     c
     f
     p
     v
       a
       c
     m
       c
       f

I was expecting the complete tag label instead of just the first letter.
Is there any way to print the whole tag label?

By the way, any suggestions and some sample code that you can provide on
how to get the data between the tags; <item> justanitem </item>, storing
justanitem to a variable.

I really really appreciate inputs on this. Thanks in advance!

The output is wrong.

What Dll are you using? libexpat.dll or libexpatw.dll?
As far as I can tell, outline.c only works with the UTF-8 version of Expat.

Accumulate data from character handler call-backs in a buffer and
store the buffer contents in a variable when another call-back (other
than to a character data handler) occurs. Then clear the buffer and repeat.

Is there no way to tell expat to parse a file that have multiple roots?

Like that:

I think the problem is that a valid XML file only has one root (by definition). Why not append a root tag to the beginning and end before parsing?

You can wrap your actual file in a wrapper that will provide the root
element:

<?xml version="1.0"?>
<!DOCTYPE log [
<!ENTITY data SYSTEM "log.data">
]>
<log>&data;</log>

log.data is:

<event time='1234' type='this'>
<detail>blah</detail><detail>blahblah</detail>
</event>
<event time='1236' type='this'>
<detail>blah</detail><detail>blahblah</detail>
</event>
<event time='2234' type='that'>
<detail>weeble</detail><detail>blahblah</detail>
</event>

Great idea!

I just have to fill the input buffer with my start root tag and parse it.
Then read my file.
Then fill then input buffer with my end root tag and parse it.

As long as each parser object is passed into Expat by only one thread
at a time, you'll be fine.  Anything else you will need to protect by
explicit locks.

Fred,

now you've confused me. Please, could you rephrase this? 

Thanks

That's not a good sign.  Appearantly I should have gone to sleep
sooner.  ;-)  Re-reading my first response certainly gives me that
impression.

 > Please, could you rephrase this? 

Each parser object can handle just one document at a time, and can
only have one call active at a time.  It doesn't really care that all
calls come from the same thread, though that's an easy way to ensure
serialization.

Message-ID: <33139.220.247.247.26.1069331127.squirrel@webmail.pair.com>

Hi,

If someone give me answers to the following two questions it is
greatly appreciated.


My first question is,
My application is receiving buffers of varying length and I need
to parse them as I receive them. Is it possible to parse these
buffers directly without calling XML_GetBuffer function to get
a buffer from expat?.

My second question is,

If the answer to the first question is yes, will the expat
delete my buffer?.

I actually tested these and got the answer to the
first 'yes' and to the second 'no'. Just asking to confirm that.

thanks in advance
damitha

Yes, just use XML_Parse(). However, this will still copy the data
to Expat's internal buffer - which Expat creates with XML_GetBuffer().
Performance-wise this does not gain you anything.
However, if you build Expat with XML_CONTEXT_BYTES undefined then
it will parse directly from your buffer, unless there were unparsed
data left from the previous buffer - in which case it will still copy
all data internally (and this would be the more likely case).

Confirmed.

Btw, the best approach performance-wise would be if your
application could use a buffer created with XML_GetBuffer().
That would avoid double copying.

Not yet. It is planned for the next-generation Expat.

Is it implemented as a specific API? No, not yet.
However, I recently added patch #835123 - check
http://sourceforge.net/tracker/index.php?func=detail&aid=835123&group_id=10127&atid=310127
which should enable pull-like operation by allowing you
to stop and resume the parser.

How to implement pull operation on top of a push
parser is described (in principle) here:

I am sure this is probably not good practice but it suits my needs. I am
currently using new (allocating memory) in the start handler. At the
termination of my program during cleanup when I try to delete the memory
that was newed in the start handler the program crashes. Why would this be?

This is definately not the right list for this either.

My C++ is a bit rusty, but offhand I don't see any reason for this to
be a problem.  Perhaps posting a short sample that exhibits the
problem will make it easier for people to figure out; creating a
shorter example that exhibits the problem may well make it easier for
you to see what's wrong.

Hi,



Expat 1.95.6



I am processing CDATA sections using my character data handler. At the

moment I get all characters except for the CR (Carriage return) character.

It is important I get all data from the CDATA section.  How can this

be achieved?



Best Regards,

Mark

Toni, thanks for the reply. I understand it a bit better now.  



However I cannot just translate all LF's to CRLF's since our data can 

contain LF or CRLF and this must be preserved.  Do you have any idea how I could solve this?



Thanks, Mark

Infact all CRs (and CRLF pairs) are converted into single LF. This is 
something that all conformant
parsers do, I believe even MSXML does this. There might be some setting in 
parser that preserves
CRs or there might not. So you must handle these at application level. 
Sometimes you can just work with (unix) style LFs, usually this isn't 
possible when working in windows and you want to "visualize" your data to 
the user though. So you need to convert them to CRLFs, nasty job, I know.

Elsewhere you could use &#13; &#10; entities (converting input CRs into 
&#13; etc - ugh!), but not in CDATA section.

I suppose you can decide to use CR or LF or CRLF in CDATA section. No? If 
not, I don't know a way to solve this, sorry.

with respect.

I my data section I replace CR and LF at save time by other caracteres that
wont be used and back to CR ou LF at reading time.
